Subject: [PATCH] soc/mediatek/mt8186: Shut down PMIC on power key long press

Currently on power key long press, PMIC will be reset. It would cause
an unwanted reset pulse in the power-off sequence. To match expected
sequence, change PMIC behavior to "force shutdown".

BUG=b:271771606
TEST=long-pressing power key doesn't trigger PMIC_AP_RST_L pulse
BRANCH=corsola
